A Comparative Study of Spacing and Integrated Nutrient Management on Growth, Yield and Economics of Okra

The present investigation was conducted at Horticultural Experimental Farm, B.A.C.A., Anand Agricultural University, Anand in kharif during 2022 and 2023. Ensuring balanced plant nutrients and spacing is essential for achieving optimal okra production. Optimal plant density supports uniform and healthy growth by effectively utilizing moisture, nutrients, and light, thereby maximizing okra yield. Single source of nutrients whether chemical fertilizers, organic manures or biofertilizers that cannot improve production, productivity and soil health. Sowing okra at 60 × 30 cm spacing observed better leaf area (433.06 and 568.01 cm2) and number of nodes per plant (15.57 and 23.46) at 60 and 90 DAS. While, maximum yield per plot (9.20 kg) and yield per hectare (14.19 t) was found in 45 × 30 cm spacing. Application of 25% RDF + 50% RDN through Vermicompost + NPK consortium 1L/ha recorded maximum yield per plot (9.41 kg) and yield per hectare (15.33 t). With respect to treatment combinations, sowing of okra at 60 × 30 cm spacing with application of 25% RDF + 50% RDN through Vermicompost + NPK consortium 1L/ha recorded the highest leaf area (458.88 and 598.27 cm2) at 60 and 90 DAS. However, maximum yield per plot (10.45 kg) and yield per hectare (16.13 t) was found in 45 × 30 cm spacing with application of 25% RDF + 50% RDN through Vermicompost + NPK consortium 1L/ha. On economic point of view, maximum net realization (218555.21 ₹/ha) and BCR (2.11) was obtained in 45 × 30 cm spacing with application of 25% RDF + 50% RDN through FYM + NPK consortium 1L/ha.
